4 constant current ic W2RV005RM dimensions precautions for use correct use ? the absolute maximum rating is th e limit value which should not be exceeded even in a flash. exceedi ng this value can cause deterio- ration of the characteristics or complete failure of the ic. ? sufficiently take into consideration the static electricity, chattering and voltage of the input to be connected when determining each input terminal. since unused input terminals may cause an undefined state in the internal circuit, connect them to a power supply (voltage = v cc or less), like i/o. ? although the device contains an esd protection circuit, static elec- tricity that exceeds the function may damage the device. when handling the device, exercise due caution by, for example, ground- ing the human body. ? due to the structure of the ic, parasitic elements are formed unavoidably. exercise due caution not to use the device in a way that activates the parasitic elem ents. for example, do not apply a voltage lower than gnd to the input terminals. ? taking the power dissipation in act ual use into consideration, per- form thermal design with a sufficient margin. when a voltage applied to the ic is high, which is due to, for example, a small num- ber of led?s driven in series, ic heat generation can be controlled by inserting a resistance and spr eading power consumption evenly. ? this ic incorporates a built-in thermal shutdown circuit. if the chip temperature rises too high, this circuit works and the output termi- nal becomes an open state. when the chip temperature returns to a normal range, the output terminal also returns to its original state. this circuit is a protective f unction for use at an emergency, so please do not use it as a regular function. ? due to potential damage, do not use product that has been dropped or that has come into contact with water. rohs directive compliance models that are indicated as being rohs compliant are free of the following six substances. lead: 1,000 ppm max. mercury: 1,000 ppm max. cadmium: 100 ppm max. hexavalent chromium: 1,000 ppm max. pbb: 1,000 ppm max. pbde: 1,000 ppm max. type (abbreviation) (max. 3.25 including burr) lot no. index mark (0.475) (unit : mm) 0.08 2.9 0.1 0.65 0.1 0.22 +0.05 -0.04 4o +6o -4o 0.145 +0.05 -0.03 0.9 (max.) 0.75 0.05 0.08 0.05 2.8 0.1 4 0.2 0.29 0.15 0.6 0.2 s s 1 4 8 5 2.62 0.99 0.35 0.65 recommended pcb layout
